Detailed Embodiments

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0021] As Figures 1 to 6 shown, a cylinder device for a circular knitting machine includes a base 2, a cylinder main body, and a connecting member 4 for fixing. The base 2 includes an outer ring wall 21 and an inner ring wall 22. A first annular groove 23 is provided between the outer ring wall 21 and the inner ring wall 22. The cylinder main body is installed in the first annular groove 23. A plurality of first clamping grooves 24 are provided at the bottom of the first annular groove 23 along the center of the base 2. A first threaded hole 25 is provided on the outer ring wall 21;

[0022] The cylinder main body includes four cylinder plates 31 joined together. Second clamping grooves 33 are provided at both ends of the cylinder plate 31. Two adjacent cylinder plates 31 are joined together by first clamping blocks 32 clamping the second clamping grooves 33 of the two cylinder plates 31 respectively. The cylinder plate 31 is in limit clamping connection with the outer ring wall 21. The bottom of the first clamping block 32 is in limit clamping connection with the first clamping groove 24. A second threaded hole 321 is provided on the first clamping block 32. The connecting member 4 is sequentially threadedly connected and passes through the outer ring wall 21, the cylinder plate 31, and the clamping block and abuts against the inner ring wall 22.

[0023] With the above structure, by clamping and arranging the cylinder main body on the outer ring wall 21 and the inner ring wall 22, and at the same time, the cylinder plates 31 of the cylinder main body are connected and joined together by the first clamping blocks 32. After all the cylinder plates 31 are placed in the first annular groove 23 at the preset positions, the first clamping blocks 32 are inserted into the second clamping grooves 33 between the two cylinder plates 31. After the first clamping blocks 32 are inserted until the bottoms of the first clamping blocks 32 are in limit clamping connection with the first clamping grooves 24, then the connecting member 4 is used. The connecting member 4 is a screw. The screw is inserted into the first threaded hole 25 of the outer ring wall 21 and the second threaded hole 321 of the ground clamping block, so that after the cylinder plates 31 are clamped and fixed by the first clamping blocks 32, the cylinder plates 31 and the base 2 are further connected and fixed by the screws, which is beneficial to more convenient installation, and the structure is stable and the fixation is reliable; if replacement is needed, since the relative height of the first clamping blocks 32 in the present utility model is higher than that of the outer ring wall 21, the inner ring wall 22, and the cylinder plates 31 of the base 2, only the screws around need to be removed first, and then the first clamping blocks 32 are taken out, and then the cylinder plates 31 can be taken out, and the replacement is more convenient.

[0024] Specifically, as Figures 1 to 6As shown, a number of limiting posts 51 are installed around the center of the base 2 along the bottom of the first annular groove 23. A limiting groove 52 matching the limiting posts 51 is also provided at the bottom of the syringe plate 31, and the limiting posts 51 are clamped and limited with the limiting groove 52.

[0025] By clamping and limiting the limiting posts 51 with the limiting groove 52, it is beneficial for the syringe plate 31 to be better fixed in the first annular groove 23 of the base 2. The structure is simple and stable, the fixation is firm, and the vibration or movement of the syringe plate 31 is prevented.

[0026] As Figures 1 to 6 shown, a number of second clamping blocks 53 are installed on the outer side of the syringe plate 31. A number of third clamping grooves 54 matching the second clamping blocks 53 are provided along the center of the base 2 on the inner wall of the outer ring wall 21, and the second clamping blocks 53 are clamped and limited with the third clamping grooves 54. Slide rails 541 are provided on the two side walls of the third clamping groove 54, sliding parts are provided on the slide rails 541, sliding grooves 531 are provided on both sides of the second clamping block 53, and the sliding parts are in sliding fit with the sliding grooves 531.

[0027] Through a number of second clamping blocks 53 provided on the outer side of the syringe plate 31, and the second clamping blocks 53 can be clamped and limited with the third clamping grooves 54. At the same time, slide rails 541 are provided, and the sliding parts are in sliding fit with the sliding grooves 531. It is beneficial to put the syringe plate 31 in more conveniently and quickly when installing the syringe plate 31 on the base 2. The second clamping blocks 53 are clamped and limited with the third clamping grooves 54, which is beneficial to the structural stability and prevents the syringe plate 31 from vibrating or shifting in the angular direction, indirectly improving the processing quality of knitting.

[0028] As Figures 1 to 6 shown, a buffer pad 6 is installed at the bottom of the first annular groove 23.

[0029] By setting the buffer pad 6, when the syringe plate 31 abuts against the first annular groove after being placed in the first annular groove 23, the impact can be reduced, and it has a good buffering effect, protecting the syringe plate 31 and the device.

[0030] As Figures 1 to 6 shown, a third threaded hole 7 for passing through and threadedly connecting the connecting piece 4 is also provided at the joint after splicing of two adjacent syringe plates 31. The first threaded hole 25, the second threaded hole 321 and the third threaded hole 7 are located on the same axis. The setting of this structure is beneficial for the screw to quickly pass through the first threaded hole 25, the second threaded hole 321 and the third threaded hole 7 in sequence and be threadedly connected, fixing the outer ring wall 21, the first clamping block 32 and the syringe plate 31 firmly. The fixation is firm, the connection is convenient, and the material of the required connecting piece 4 is simple and easy to find.

[0031] The bottom of the first clamping block 32 is provided with a third clamping block 8, and the third clamping block 8 is in limit clamping connection with the first clamping groove 24. The setting of this structure is beneficial to the first clamping block 32 being firmly fixed between the two syringe plates 31 and having a better limiting effect.
